So sometimes our web servers (Windows Server 2008, IIS 7.5) will randomly get this error on a really really old .net 2.0ish asp.net/classic asp web site that we have.因此，有时我们的 Web 服务器（Windows Server 2008、IIS 7.5）会在我们拥有的非常旧的 .net 2.0ish asp.net/classic asp 网站上随机出现此错误。

Normally an IIS reset will clear up the issue, but this issue is now starting to affect our production servers (can't really IIS reset these in the middle of the day) and it also seems to be happening more often every where else.通常 IIS 重置会解决这个问题，但这个问题现在开始影响我们的生产服务器（IIS 不能在中午真正重置这些），而且它似乎在其他地方更频繁地发生。

So I've been looking into possible fixes for this issue, but the only one that seems to be popping up everywhere is that if I grant NETWORKSERVICE/IIS_WPG full control over the temporary asp.net files it should just fix itself.因此，我一直在寻找针对此问题的可能修复方法，但似乎无处不在的唯一修复方法是，如果我授予 NETWORKSERVICE/IIS_WPG 对临时 asp.net 文件的完全控制权，它应该自行修复。 Last I checked, this wasn't really a good idea as you really didn't want your web applications to have full control over anything (especially not on a production web server).最后我检查了一下，这不是一个好主意，因为您真的不希望您的 Web 应用程序完全控制任何东西（尤其是不在生产 Web 服务器上）。

Any guidance on this issue would be appreciated.任何有关此问题的指导将不胜感激。

Thanks, Alex谢谢，亚历克斯

I think your problem is with IIS, in regards with what permission it has to folders(eg. project folders).So check your application which application pool its in. So you can give the appropriate rights to the account in that pool.我认为您的问题出在 IIS 上，关于它对文件夹（例如项目文件夹）的权限。因此，请检查您的应用程序所在的应用程序池。这样您就可以为该池中的帐户授予适当的权限。 By default in IIS7, the account is NETWORK SERVICE.默认情况下，在 IIS7 中，帐户是 NETWORK SERVICE。

Then you would essentially go to the relevant folders and allow read/write access or whichever needed to the account.然后，您基本上会转到相关文件夹并允许读/写访问权限或帐户所需的任何权限。
